I read it this way too. Mnoren can do it without a gate (effectively meaning they can automatically create a "gate" whenever they want). I also always assumed that any Mnoren "gate," since they didn't go to the trouble of "creating" an actual gate, would disappear when the Mnoren left.

But once a gate is created, the only restrictions on using it were based on the size of the gate and what conditions (if any) the creator put on it.
